// 算法核心语句for(k=1; k<=n; k++)// 从k中转换for(i=1; i<=n; i++)  for(j=1; j<=n; j++)  if(e[i][k] <div>    && e[k][j] <div>    && e[i][j] <div>    e[i][k] + e[k][j])    e[i][j] = e[i][k] + e[k][j];    if(e[i][j] <div>    && e[k][j] <div>)if(e[i][j] <div>)

这段代码涉及动态的数组赋值逻辑,通过双重循环遍历矩阵中的每个元素,并在特定条件下进行数组赋值操作。代码结构清晰,主要循环变量包括kij,分别对应数组的外层、中层和内层循环。

核心语句中的条件检查逻辑如下:

  • 检查e[i][k]e[k][j]e[i][j]的值是否小于某个阈值(表示未赋值状态)
  • 如果上述条件满足,执行数组赋值e[i][j] = e[i][k] + e[k][j]
  • 以上操作只在满足条件时执行
  • 这种结构保证了在动态赋值过程中,只有在特定条件下才会更新目标位置的数组元素,避免不必要的计算或错误操作。

    代码逻辑简明,循环结构清晰,便于理解和优化。
